Toxic! Just like #Trump!

Dead ducks add to Trump’s reflecting pool drama

A local wildlife organization is performing necropsies on ducks found dead near the Lincoln Memorial Reflecting Pool.

Excerpt: "A local wildlife organization collected two deceased ducks, found at a pond adjacent to the pool Sunday. The same day, a Washington Examiner journalist documented another dead adolescent duck floating in shadow of the Lincoln Memorial. The presence of deceased waterfowl has sparked speculation of #ToxicAlgae, sometimes known as blue-green algae, or #cyanobacteria, in the lime-green gunk that swiftly proliferated after the Trump administration installed a commercial pool liner earlier last month."

Working out how photosynthesis evolved.

"The most recently identified Gloeobacteria species, Anthocerotibacter panamensis, harvests light using a different set of proteins than modern cyanobacteria — but converts sunlight into chemical energy within protein complexes that vary only slightly from those in other Gloeobacteria. These traits add new color to the long, strange evolutionary story of photosynthesis."

#GreatGreenWall 2.0: #China is #geoengineering #deserts with blue-green #algae
These specially selected strains of #cyanobacteria can survive extreme heat and drought for long periods, according to China Science Daily on Thursday. When rain finally comes, they spring to life, spreading rapidly and forming a tough, biomass-rich crust over the sand. This living layer stabilises the dunes and creates the perfect foundation for future plant growth.

Earth-like #planets orbiting small, red #stars known as M-dwarfs are often considered the right size and at the right distance from their sun to harbor #life.

However, these worlds may not have the right kind of light to support multicellular organisms.

Here on Earth, #plants and #bacteria turn sunlight into energy through #photosynthesis, releasing oxygen as a byproduct.

During the Great Oxidation Event around 2.3 billion years ago, significant quantities of #oxygen began to accumulate in our #atmosphere, eventually reaching levels capable of supporting multicellular life.

According to our understanding, a similar process would have to occur on other planets for complex life to start evolving.

#Photosynthesis requires a specific kind of light from 400 to 700 nanometers that plants, #algae and #cyanobacteria need to thrive.

Although it was known that light from M-dwarf stars like TRAPPIST-1 is mostly #infrared, which falls outside this range, what was unknown was how this would slow down the evolutionary clock.

By comparing light from these red stars to our own sun and modeling the oxygen production of various #bacteria, redearchers calculated that because these stars produce so little usable energy, the accumulation of oxygen would be far too slow.

Potentially, on a #planet like TRAPPIST-1e, it would take 63 billion years in a worst-case scenario to reach the oxygen levels seen on Earth through photosynthesis.

When large quantities of brown #algae are repeatedly #washedashore over an extended period, my first question as an acarologist is naturally which interesting, and possibly phoretic, terrestrial #organisms, such as mites, are specifically #adapted to these #conditions. But these algae are a phenomenon with #ecological #repercussions that must be understood. It is particularly interesting, thus, that it is the #phosphorus content that affects #symbiotic #cyanobacteria, which promote algal growth

Researchers at McGill University have identified #bacteria that can indicate whether a blue-green #algae ( #cyanobacteria ) bloom is likely to be toxic, offering a potential water-safety early warning system.

Carlos J. Pardo-De la Hoz et al. studied the evolutionary history of the cyanobacteria Nostoc, demonstrating that rapid radiations are major contributors to the complex speciation history of this group.

The #ocean’s most abundant #microbe is near its breaking point

Tiny ocean microbes called #Prochlorococcus, once thought to be #climate survivors, may struggle as seas warm. These #cyanobacteria drive 5% of Earth’s #photosynthesis and underpin much of the marine #food web. A decade of research shows they thrive only within a narrow #temperature range, and warming oceans could slash their #populations by up to 50% in tropical waters.
